Fornell-Larcker criterion

Source: R/helper_assess.R
calculateFLCriterion.Rd

Computes the Fornell-Larcker matrix.

Usage

calculateFLCriterion(
  .object              = NULL,
  .only_common_factors = TRUE,
  ...
  )

Arguments

.object

An R object of class cSEMResults resulting from a call to csem().

.only_common_factors

Logical. Should only concepts modeled as common factors be included when calculating one of the following quality criteria: AVE, the Fornell-Larcker criterion, HTMT, and all reliability estimates. Defaults to TRUE.

...

Ignored.

Value

A matrix with the squared construct correlations on the off-diagonal and the AVEs on the main diagonal.

Details

The Fornell-Larcker criterion (FL criterion) is a rule suggested by Fornell1981;textualcSEM to assess discriminant validity. The Fornell-Larcker criterion is a decision rule based on a comparison between the squared construct correlations and the average variance extracted (AVE).

The FL criterion is inherently tied to the common factor model. It is therefore unclear how to meaningfully interpret the FL criterion in the context of a model that contains constructs modeled as composites.
